MEANS FOR IMPREGNATING MATCH SPLINTS Patented Dec. 23, 1930V UNITEDSTATES PATENT oF-Flc's i CARL C. HAFERKAMP ANDV WILLIAM J. ELDER, 0FOSWEGO, NEW YORK, ASSIGNORS TO THE DIAMOND MATCH COMPANY, OF CHICAGO,ILLINOIS, A CORPORATION OF ILLINOIS MEANS ronrnrnnenarrne MATCH sPLrNTsAppiication med october 1s, 192s. serial No. 313,300.

This invention relates to match making machines, and particularly tomeans ar# ranged in coi-operative' relation to a match splint carrier`whereby the match splints borne by the latter are economically andeiectively impregnated with a 'solution of material adapted to renderthe splints-nonsplint carrier of a match machine 'and di-V rectedytoward [the travelling depending splints; means for supplying asolutionA of impregnatin'g material, 'and also air under pressure, tothe said nozzle, and means for oscillating the nozzle in a Vplaneparallel, 0r substantially so, to the path of the adjacent splintsduring thetravelV of the carrier.

In the preferred embodiment of the present invention the spraying nozzleis'i'nounted and adapted to oscillate in. frontof` a verticallyextending portion of the carrier to the end that the so'lution'ivill beprojected from thenozzletoward and `against the horizontally-disposedsplints andthe opposing vertical faceof the carrier plates, thuspermitting'the resulting moisture on the plates to flow. freelytherefrom into4 a suitable drip pan and consequently minimizing the saltaccretion and the corrosive action of; the solution on the plate. Thependant position of the spraying nozzleensures the `gravitation of thesolution thereto from an elevated source of supply. It alsoenables thesuspension of thernozzle from and directly below a horizontal'actuatingshaft, thus reducing thestresses 1n the supporting arm of thel nozzle asWel-l as in the shaft. ,More-Y over the use of ahorizontal'actnatiiigshaft obviates the useof thrustbearings there for,and the location of the bearings and the actuating parts for the shaftabove the nozzle, protects the -said bearings and parts frointhe;injurious ell'ects of `the salt solution ejected from the nozzle. Inthis construction there is provided for the spraying element asuitablecasing to Which access can befreadily had, and alsoL meanswhereby s'liver's'and imperfect splints blown from the carrier plates bythe force of the spray esca-pe the nozzle and its operating' devices andfall directly upon a detachable screen Which is located above the drippan, Whe'nce they can bereadily removed.

The invention also comprises novel features of construction andcombinations of parts' ,wliereby other advantages are gained, as will behereinafter described; the scope of the invention then being 'dened inthe appended claims.

` 'Referril'ig tothe drawings, 10 designates-a portion otra 'splintcarrier ot' a continuous match machine which carrier, comprises anendle'sschain of per'forated plates in which i the Ysplints are endvviseinserted and thereby rigidly heldin spaced parallel rows, This carrierin its progress to andabove `the usual paralfin tank 1l is looped Vovera pail' O .f spaced-apart rails 12pt generalugU-*formation supported bycross-bars 13, Carried by the sov ich

framework 14 of the machine. The tops of the rails l2 are preterablyformed with gaps 15 into which entend a pair of idlers 16 that affordrolling` contact for the carrier. These idlers are loosely n'iounted ona cross-shaft l? supported by suitably-disposed brackets 18 on theframework. An arched plate i9 sujiported beneath the path of the carrierloop, in the vicinity of the idlers, serves to intercept and shed Wastematerials which may fall from the carrier, thus preventing theirdropping into the underlying mechanism. This plate 19 is affixed tocross-rods 20 mounted in and between depending lugs 2l on the respectiverails 12. (See Fig. 4.)

The leg 22 of the carrier loop, with the rows of match splints projecting horizontally therefrom, travels upvvard in a vertical path, asseen in F ig. 4, such leg being guided and supported in suitabletrackways hereinafter described.

Mounted to swing in proximity to and paralle with the path of theupwardly progressing splints, throughout the Width of the carrier, is anozzle 23 by means of which a solution of impregnating material, such asammonium phosphate, is edectively sprayed upon such splints throughoutthe Width of the carrier. rlhis nozzle is supported at the toot of apendulous arm 24 fast on a horizontal rock-shaft- 25 having its bearings26 in a suitable housing 27 on an L-frame 28 which is bolted to a pairof transverse frame bars 29. Hence, not only are the stresses in thesupporting arm 24 and shaft 25 reduced to a minimum, but the nozzle, asWell as the shaft and its operating parts, is away from the path ofslivers and broken splints falling from the carrier.

riChe nozzle is provided with solution and air inlet ports 30, 31,respectively, in operative connnunication with a discharge opening 32from Which the impregnating solution is ejected by air, under pressure.The ports 80, 3l are connected by pipes 33, 34 with ports 35, 36,respectively, in a` flanged head 37 which, together With the arm 24, isbolted to a flange 88 on the rock-shaft 25. The port 36 has affixedtherein a fiexible pipe or hose connection 39 which leads to a suitablesource of air supply, and the port has afhxed therein a throat member 40which depends from a bracket 4l bolted, as at 42, to the bearir housing43 ofthe L-frame 2e. The throat member is connected by means of a pipe44 with a solution supplying unit which is or may be of the charactershown, and described in the patent aforesaid. Such unit preferablyincludes a tank 45 containing impregnating solution which is suppliedthereto through a pipe 46 having a suitable shut-off valve 47. It alsoincludes a roll 48 which rotating in the tank and its contents carriesup a peripheral film of the solution and deliversit to an inclinedtrough 49, from Which it flows into a funnel 50 in communication withthe pipe 83 and gravitates thence into the port 30 of the nozzle.

From the foregoingit will be seen that during the oscillation of thenozzle 23 air under pressure passes through the port 51 and across thedischarge opening 32 of the nozzle, and by contact With the liquidflowing from the port 30 reduces the liquid to a. line sp1-a y or mistand projects it in that condition Jfrom the mouth of' the nozzle andtoward and across the vertical splint bearing face of the progressingcarrier.

The rock-shaft 25 and the roll 48 are concurrently actuated. To this endthe rockshaft is provided With a crank arm 5l which is connected bymeans of a rod 52 to a crankdisk 58 on av shaft 54 which is geared withthe shaft 55 of an electric motel' 56 supported on the L-frame 28. Theshaft 54 is also equipped with a sprocket Wheel 57 which is operativelyconnected by means of a chain 58 with a similar wheel 59 on the shaft ofthe roll 4S.

During the operation of the match machine the moisture deposited on theface ofl the carrier plates by the spray fiovvs down such plates anddrips into a suitable receptacle, thus minimizing the salt accretion andthe corrosive action of the solution on the plates, as previouslymentioned. This receptacle preferably comprises a pan 60 which underliesthe vertical leg 22 of the splint carrier, the pan being provided Withbasal lugs 61 which are supported on brackets 62 on the framework of thematch machine. In one Wall of the pan is a pipe fitting 63 affording afluid passage leading to a lateral overflow pot 64. In this pot is anupstanding nipple 65 which is connected by means of a pipe 66 with theinlet of a suitable pump 67, the outlet whereof is connected by means ofa pipe 68 with the solution supply pipe 46 at a level below the valve 47of the latter. Hence during the 0peration of the apparatus the liquidflowing into the pan is continuously pumped back to the tank. The tank45 is provided with an overflou7 pipe 69 connected with the pipe 66 sothat the overflow from the tank passes to the pump and is pumped back tothe tank (See Figs. 1 and 2.)

The pan 60 is equipped with a detachable rectangular screen 70 uponWhich fall tlu` slivers, etc., blown from the carrier plates by the.force of the spray :from the Oscillati nozzle, which screen is readilyremovable for cleaning as occasion may require. The top of the pipenipple 65 Within the overflow pot (,i-l is so positioned that thesolution level in the drip pan is normally Well above the screen, thuspreventing the crystallization of the impregnating salt on the screenand the conf-1cquent plugging of the meshes.

A suitable protectve casing extends from the drip pan to the top of theloop of the splint carrier, so as to enclose the adjacent leg 22 of theloop, and also the pendulous spraying element. This casing preferablyVcomprises four substantial cornerv posts 7l, 72 adn-:ed to and risingJfrom the respective sides ot the pan. One 'pair 7l of posts extendadjacent to and parallel with the bach of the carrier and terminate incurved portions 27?; overlying the adjacent portions oi' the track rails12,'and the vother pair 72 are fastened at their upper ends to theextremities of the curved portions "7i-l, thus affording a. rigdskeleton trame. This frame supports Vthe side, front and bach wallsrespectively ot the casing, the sidewalls extending from the bottom tothe top ot' the trame, and the remaining walls terminating at .lowerlevels as seen. The side walls are provided with upper and lower hingeddoor sections T4, 75, respectively, and the frontend bach walls 76, 77are hingedly mountedv on the adjacent posts, thus enabling accessvto bereadily had to the interior of the casing for purposes of inspection,repair, etc.

The posts 7l cooperate with spaced v cal guide-strips @"8 to atlord thetraclrways hereinbetore mentioned 'lier the leg` ol the carrier loop -inits upward travel, which guide-strips are conveniently fastened, as atT9, to the adjacent side doors 75. l

As a simple and eiiicientV means to contribute to the supportA andguidance oi' the body of the vertically-moving leg of the carrier loop,ssaced-apart vertical guide bars S0 are arranged adjacent the path oftheimperiorate front portionsiSl 6) of the carrier. These bars are fixed attheir respective ends to horizontally-disposed U-bar 82 carried by theposts 72 of the casing, the upper bar being suspended by strapsdepeiiding from the supporting.brackets Si of the stationary guide-rails12 previously described.

In order toiinininiize the amount of moisture and salt accretions ontheback of the carrier plates, inci ,ent to the spraying operation, aivertically disposed'partition pla-te having a lnlsal'deilecting ledge 85supported within the casing adjacent to and partiel *ith the bach oi thevertical leo' ot' the carrier loop, and a transverse troiigh 8G hat#ing` at one end a spout d? leading to the drip pan, is arranged belowthe partition 84. Any spray going through the oeriiorations of thecarrier plates or between the gaps of adjoining plates runs down thepartition and dri es into the trough 85, which trough iii-turn,discharges its contents past the splint carrier into the drip pan.

The partition plate 8l is yieldabl f supported on the adjacent door TSof the casing in such manner that when such door is closed the plate iscaused to bear 'liatwise against the back of the carrier.` Accordinglythe plate Si is connected to the door by a pair oi' pivoted links 88having depending tails '8D adjacentthe inner side ot the door, whichdoor when closed bears against the tails swings the linls in' a mannerto press the plate Sil closeI to the opposing side Vot the carrier. (SeeFigs. Ll and y T he trough cl-t3 is preferably supported at its ends inpockets 90 termed adjacent the lower ends of the side posts il. it alsosusained by straps 9i which depend 'from a cross-bar 92 connecting thelower ends oil the posts 7l, which bar affords a convenient support forthe hinges oli-an overhan;l f cover-section 98 for an adjacent project;portion of the dripfpan wherein theV splint carrier is flexed in itspassage from a horizontal to vertical position.
